Maintenance of garlic (Allium sativum L.) genetic resources has had a long tradition in the Czech Republic. The collection was founded in 1951 and its current holder is the Crop Research Institute, Department of Vegetables and Special Crops in Olomouc. The collection consists of 613 genotypes. The oldest genotype was acquired in 1954. The collection has been evaluated according to the Descripto...

Aiming at the problems of difficult support mining roadway under goaf close distance coal seam, obvious large deformation, and long-term continuous deformation surrounding rock, an advanced bolt-grouting system is proposed. The can effectively solve problem from design system, construction monitoring evaluation realize intelligent support. Based on actual engineering background 29204 working fa...

this research was carried at the university of reading in 1999. the aim was to estimate the effects of 18 hd-1 (long-day, ld) and 12 hd-1 (short-day, sd) light exposure duration of plants before bolting or flowering on time to bolt and flower in two bolting susceptible (bsg, ic1) and bolting resistant (brg, saxon) genotypes of sugar beet. so, two experiments were conducted. the experiments were...

by Philip Ebert & Simon Robertson forthcoming in M. McNamee (ed) Philosophy, Risk and Adventure Sports, Routledge In this paper we examine a recent version of an old controversy within climbing ethics. Our organising topic is the ‘bolting’ of climbing routes, in particular the increasing bolting of routes in those wilderness areas climbing traditionalists have customarily believed should remain...

Leaves are the major biomass-producing organs in herbaceous plants and mainly develop during vegetative stage by activities of shoot apical meristem. There is a strong correlation between leaf number and bolting, a characteristic phenotype during the transition to reproductive phase in Arabidopsis thaliana. In order to study interactions between leaf number and bolting, we isolated a Landsberg ...

this research was designed to identify garlic (allium sativum l.) bolting clones and determining the relationship between their morphological traits and bolting capacity by using statistical methods of analysis of variance, comparison of means, correlation coefficients, factor analysis, stepwise regression, path analysis and cluster analysis. traits including flowering ability, number, length a...

to evaluate general and specific combining ability for resistance to bolting and cercospora leaf spot, 36 hybrids derived from crosses between 9 sugar beet lines along with four checks were planted in safiabad agricultural research center (dezful) in 2008-2009. the experimental design was a triple lattice design with three replications. analysis of variance showed significant differences among ...

Support failures in mine drifts represent potential hazards that threaten underground safety and productivity. The aim of this study is to determine the reliability index associated with rock supporting elements used Ridder-Sokolny mine, an located East Kazakhstan. Numerical simulations drift support First Order Reliability Method (FORM) were employed carry out analysis. Several cases considere...

LFYgene plays important roles in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY gene in Arabidopsis resulted in the formation of late flowering and highly branching phenotype. In this paper, we investigated some physiological and biochemical properties of the transformantsthat were down-regulated LFY gene expression to dela...

This research was conducted to evaluate the effect of temperature and photoperiod treatments on the bolting and bulb formation of three local garlic cultivars (cvs) in two consecutive years. Naturally vernalized plants of cvs G107, G025 and G064 were transplanted into growth chambers and subjected to various combinations of temperature [T15/10, 15°C/10°C; T20/15, 20°C/15°C and T25/18, 25°C/18°C...
